Select the correct statements regarding Asynchronous Transfer Mode (ATM): a. ATM is a fixed-length cell standard that supports v
oice, video and data b. ATM is connection-oriented c. ATM offers predictability regarding latency; therefore ATM can offer quality-of-service (QoS) to users d. All of the above are correct
Asynchronous Transfer Mode is a fixed-length cell structure which allows cells to support voice, video and data. Voice data can be converted to packets and shared with large packet data. Because voice packets, encounter queuing delays, they ought to be of the same size or length.
ATM provides a route between two end points and that is why it can be said to be connection oriented. There is an ease of switching in hardware because of the fixed structure of the ATM. It also offers predictability regarding latency which could be either high or low. So, all of the above satisfy the mode of operation of the Asynchronous Transfer Mode.
